Optical geodesic measurement device

Abstract

The invention relates to an optical geodesic measurement device. The optical geodesic measurement device can provide a horizontal true angle. The optical geodesic measurement device comprises an optical module and an orientation module. The orientation module comprises a host computer module and a calibration module. The orientation module is utilized for horizontal true calibration and provides a true angle for the optical module. The optical module has a physical connection with the host computer module. The optical module has functions same as functions of a well-known total station. The orientation module adopts a real-time differential GPS system and comprises the host computer module and the calibration module. The host computer module is utilized as a real-time differential GPS movement station and is installed on the optical module. The orientation module is utilized as a real-time differential GPS base station. After difference, a horizontal true angle is written in an internal memory. When an optical lens aims at a marker of the orientation module, a direction arrangement button is triggered, and the optical geodesic measurement device can obtain a horizontal true angle of the orientation module relative to the host computer module and utilize the horizontal true angle as a horizontal direction reference angle.

Description

Technical field [0001] The invention relates to an optical geodetic measuring device, in particular to an optical geodetic measuring device that can provide a horizontal true angle. Background technique [0002] At present, the known optical geodetic equipment includes theodolite and total station, wherein the total station is a ranging equipment loaded on the basis of the theodolite, and its angle measuring principle is the same as that of the theodolite. Whether it is a theodolite or a total station, the vertical true direction angle is obtained through the gravity component, but the horizontal true direction angle (the horizontal angle relative to true north in the earth coordinate system) cannot be provided. When performing geodetic surveying, if you want to obtain the horizontal true angle of the target, you need to use a compass or differential GPS. When using a compass, it is necessary to know the local magnetic declination angle to obtain the horizontal true directi...
